Capstone Equities Signs UK AI Tenant to First U.S. Location

Capstone Equities, its partners Rugby Realty and Republic Investment Company, and JLL announced today that Conduct AI will open its first U.S. office at 140 Crosby St., a boutique Class A office building in Manhattan’s SoHo neighborhood. The lease encompasses the entire 6,705-square-foot third floor and represents the first transaction at the property since Capstone Equities took ownership.

Founded in London in 2024, Conduct is building an AI operating system for enterprise software, using agentic AI to help businesses understand, operate and transform complex enterprise systems. The company raised $60 million in its Series A funding round in June and is expanding its engineering and go-to-market teams as it grows internationally. Its new SoHo headquarters will mark its first permanent U.S. location and accommodate more than 60 employees.

The transaction comes as Capstone Equities prepares to make new investments in the property, including a renovation of its communal rooftop deck.“Signing a fast-growing company like Conduct AI as our first new tenant speaks to the appeal of 140 Crosby and the kind of companies this property attracts,” said Daven Roshan, Director of Acquisitions at Capstone Equities.

JLL Executive Managing Director Clark Finney, Director Alex Riguardi and Senior Associate Dana Goldman represented Capstone Equities. Max Mond and John Brennan of Savills represented Conduct AI.
